Zymomonas mobilis is a rod shaped gram negative bacterium that can be found in sugar rich plant saps. It is usually 2-6μm long and 1-1.4 μm wide, but this can vary significantly. In high CO2 or ethanol concentrations slime and granular layers have been see around the cell. It has been isolated from sugar cane as well as alcoholic beverages such as African palm wine; it is also known to cause cider sickness and spoiling of beer. However, the spoiling of beer is very limited due to its optimal temperature range of 25-30°C. It is being studied for its ability to ferment sugar to ethanol. Its ability to efficiently ferment carbohydrates using the Enter-Doudoroff pathway makes it an attractive candidate for producing bioethanol for fuel. It has also shown a high growth rate, tolerance to ethanol as well as being amendable to engineering [1] [2]. | |||
